Sticky cleaner
This invention provides a sticky cleaner used for removing organic dirt deposited on an article surface. The sticky cleaner comprises a dirt-collecting member that collects the organic dirt upon contact with the article surface. The dirt-collecting member has an acrylic PSA in an area that comes in contact with the article surface. The dirt-collecting member exhibits a hardness of 90 or less in the area that comes in contact with the article surface.
1. A sticky cleaner used for removing organic dirt deposited on an article surface,
the sticky cleaner comprising a dirt-collecting member that collects the organic dirt upon contact with the article surface, wherein
the dirt-collecting member has a pressure-sensitive adhesive in an area that comes in contact with the article surface, and
the pressure-sensitive adhesive has a triolein absorption of 0.05 mg/mm 3 or greater.
2. The sticky cleaner according to claim 1 , wherein the area that comes in contact with the article surface in the dirt-collecting member has a hardness of 90 or less.
3. The sticky cleaner according to claim 1 , wherein the pressure-sensitive adhesive has a thickness of 200 μm or greater.
4. The sticky cleaner according to claim 1 , wherein the dirt-collecting member comprises a support member on the backside of the pressure-sensitive adhesive.
5. The sticky cleaner according to claim 4 , wherein an acrylic resin is used as a material forming the support member.
6. The sticky cleaner according to claim 1 , wherein the dirt-collecting member constitutes a columnar rolling member and the pressure-sensitive adhesive forms the outer circumferential face of the rolling member.
7. The sticky cleaner according to claim 1 , wherein the pressure-sensitive adhesive comprises an acrylic block copolymer.
8. The sticky cleaner according to claim 1 , wherein the pressure-sensitive adhesive comprises a plasticizer.
9. A sticky cleaner used for removing organic dirt deposited on an article surface,
